The project is connected with development of the effective catalysts on the base of metal oxides on activated carbon surface for removal of CO from hydrogen. Firstly, the activation of cobalt supported catalysts by hydrogen was established. XPS method shown that this fact is connected with the cobalt valence state chanche.
The influence of the method of supporting of the cobalt on catalytic activity of prepared samples was shown. The most active is catalyst was synthesised on the base of acetylacetonate cobalt in organic medium. By means of methods XPS, SEM, AFM was established that this fact was connected with Co-nanoparticles formation in this process.
It was establishes that modification of activated carbon by nitrogen, phosphorus and boron heteroatoms influences on surface electronic state and active component structure. By means of AFM method was shown that simuktaneous nitrogen and oxygen introduction in AC permits to obtain separate nanoparticles of cobalt oxide. The different methods of heteroatoms introduction in carbon matrix were studied.
The modification of cobalt catalyst suppoted on AV by additives of transitions metals was realized and the increase of their activity and stability was shown. The opimal ratio of active components of AC surface was established.
The composition and preparation method of active catalyst on activated acrbon support of Co removal from hydrogen wich determine the high activity and selectvity at reaction temperature low that 100 0C were created. It was shown that these catalysts can be used at the presence of water and carbon dioxide in reaction mixture.
